Running the ActiveX cleanup utility in check mode (no options)
Running the uacflchk utility in check mode (no options) returns a listing of the relevant registry entries, dependencies, conflicting files, and missing files. These messages tell you where the problem lies, so you can take the appropriate action.
You should run the utility in check mode first, to ensure that you take any necessary action before running the tool in clean mode.
